OP

Quoted from mcluvin:

I just did this with my CR-V which has been consuming oil for the last 50K miles or so. I've read it is common for the oil control rings to get stuck on GDI engines. Anyway, pulled the plugs, hit the cylinders with a couple shots of PB Blaster. Waited a bit then poured a couple ounces of Chemtool B-12 in each cylinder. Waited until it all drained. This took anywhere from a couple of hours to roughly 8 for one cylinder. Followed this up with a couple ounces of Maxlife ATF in each cylinder and let soak overnight. One cylinder drained on its own. I had to suction the other 3. Turned it over a few times with the plugs out (lots of carbon bits on the towel covering the holes). Installed the plugs, then cranked it up and let idle for 15 minutes (some white smoke), then changed oil and filter. Oil was f'n nasty, pitch black. I've got ~100 miles on it post piston soak and it feels like a new car. Acceleration is like I remember. Time will tell if the oil consumption is resolved. Crossing my fingers...
